BOSTON -- For participation in the upcoming State Primary Election, the last day to register to vote, to change a voting address, or to change one’s political party is Wednesday, August 20, 2014. The State Primary Election will take place on Tuesday, September 9, 2014.

In order to accommodate prospective voters, the Boston Election Department in Room 241, City Hall, will remain open until 8:00 p.m. on August 20. Those wishing to register in person after 5:00 p.m. should enter City Hall from the Congress Street side (directly opposite Faneuil Hall).

Mail-in registrations must be postmarked no later than August 20. Those registrants using the US Mail should remember that the zip code for City Hall is 02201. In the past, the Election Department has seen registration forms delayed due to the use of the wrong zip code. Voter registration forms can also be found at local branch libraries.

Mail-in registration forms can be printed out from the City of Boston website: www.boston.gov/elections. Voters can also check their voting status by using the Voter Registration Search tool on the same website.

In Primary elections, declared party members (Democrats and Republicans) must take the ballot of their political party. Unenrolled (no party) voters may choose either ballot. Voters affiliated with other political designations do not participate in Primary elections.

The following political offices will be on the ballot this year: US Senator, US Representatives (Congressmen), Governor, Lieutenant Governor, Secretary of the Commonwealth, Attorney General, Treasurer and Auditor. State Senators and Representatives will also appear on the ballot, as will the Governor’s Council. Finally, Suffolk County District Attorney, Sheriff, and Register of Probate.
